General Motors announced six more recalls today, totalling 717,950 newer-model U.S. vehicles for a variety of defects.

That brings the number of GM recalls this year to 60, totaling 26.41 million vehicles.

GM says it knows of three crashes and two injuries, but no deaths, linked to the new recalls.

The automaker sees the latest round of call-backs as evidence it's continuing to strictly police itself on safety issues.

"These recalls signify how we've enhanced our approach to safety," said Jeff Boyer, vice president in charge of global vehicle safety. "We are bringing greater rigor and discipline to our analysis and decision making. If we identify an issue â?? large or small â?? that might affect the safety of our customers, we will act decisively."

"It must be a little easier for the company to continue in this direction, knowing that the numerous recalls have not" hurt sales or resale and trade-in values of GM vehicles, says Eric Ibara, director of residual values for Kelley Blue Book's KBB.com.

GM and Ford Motor report second-quarter earnings early tomorrow. GM has said it will take a $1.2 billion charge to pay for second-quarter recalls. Analysts expect it to show strong results nonetheless. Wall Streeter Ryan Brinkman at JP Morgan forecasts "Suburban-size" GM profits on North American operations.
